                          MEDIUM-TERM NOTES, SERIES E

                            -----------------------

                      EQUITY-LINKED NOTES DUE JULY 5, 2002
                       based on the Nikkei Stock Average

Each note will pay 100% of its principal amount of $10,000 at maturity. The
notes will also pay a supplemental redemption amount, which may be zero. The
supplemental redemption amount will be based on 80% of the percentage increase
in value, if any, over the life of the notes of the Nikkei Stock Average, which
we refer to as the Nikkei 225.

o    The issue price of each note is $10,000 (100% of the principal amount).

o    We will pay 0.25% per year interest on the $10,000 principal amount of
     each note. Interest will be paid on July 6, 2001 and July 5, 2002.

o    At maturity, you will receive the principal amount of $10,000 per note
     plus any supplemental redemption amount.

o    The supplemental redemption amount is based on the percentage increase in
     value, if any, at maturity of the Nikkei 225. If the value of the Nikkei
     225 at the maturity of the notes is higher than 16,338.70, which is the
     value of the Nikkei 225 on June 14, 2000, the date we offered the notes
     for initial sale to the public, then you will receive a supplemental
     redemption amount per note equal to 80% of the percentage increase of the
     Nikkei 225 times $10,000.

o    However, if the value of the Nikkei 225 at maturity is not higher than
     16,338.70, then you will not receive any supplemental redemption amount,
     but you will still receive the principal amount of the notes.

o    Investing in the notes is not equivalent to investing in the stocks
     included in the Nikkei 225.

We may not redeem these notes prior to maturity other than under the
circumstances described under "Description of Notes - Tax Redemption" in the
accompanying Prospectus Supplement.

We will issue the notes in bearer form only. You may not exchange notes in
bearer form at any time for notes in registered form. Notes in bearer form are
subject to U.S. tax law requirements and you may not offer, sell, resell or
deliver the notes within the United States or its possessions or to a U.S.
person, except in certain transactions permitted by U.S. tax regulations.

You should read the more detailed description of the notes in this pricing
supplement. In particular, you should review and understand the descriptions in
"Summary of Pricing Supplement" and "Description of Notes."

The notes involve risks not associated with an investment in conventional debt
securities. See "Risk Factors" beginning on PS-5.

                         SUMMARY OF PRICING SUPPLEMENT

     The following summary describes the notes we are offering to you in
general terms only. You should read the summary together with the more detailed
information that is contained in the rest of this pricing supplement and in the
accompanying prospectus and prospectus supplement. You should carefully
consider, among other things, the matters set forth in "Risk Factors."

     The notes offered are medium-term debt securities of Morgan Stanley Dean
Witter & Co. The return on the notes is linked to the performance of the Nikkei
Stock Average, which we refer to as the Nikkei 225. These notes combine
features of debt and equity by offering at maturity 100% protection of the
issue price with the opportunity to participate in the upside potential of the
underlying Nikkei 225. However, we may also call the notes prior to maturity.

                                   The Notes

Each note costs $10,000            We, Morgan Stanley Dean Witter & Co., are
                                   offering our Equity-Linked Notes due July 5,
                                   2002 based on the Nikkei Stock Average. The
                                   principal amount and issue price of each
                                   note is $10,000. We will pay you at least
                                   the principal amount of $10,000 at maturity.

0.25% interest on the              We will pay interest on each note, at the
principal amount                   rate of 0.25% of the principal amount per
                                   year.

Payment at maturity                Unlike ordinary debt securities, the notes
                                   do not pay interest. Instead, you will
                                   receive the principal amount of $10,000 per
                                   note plus a supplemental redemption amount,
                                   if the value of the Nikkei 225 increases
                                   over the life of the notes.

                                             100% Principal Protection
                                   Unless we have called the notes, we will pay
                                   you at least $10,000 at maturity, plus the
                                   supplemental redemption amount, if any.

                                        The Supplemental Redemption Amount
                                   The supplemental redemption amount will be
                                   equal to the percentage increase of the
                                   Nikkei 225 multiplied by $10,000. The
                                   supplemental redemption amount will be
                                   calculated as follows:

                                        Final Index Value - Initial Index Value
                     $10,000   x 0.80 x ---------------------------------------
                                                  Initial Index Value

                     where,
                     Initial Index Value = 16,338.70, which is the closing value
                                           of the Nikkei 225 on June 14, 2000,
                                           the date we offered the notes for
                                           initial sale to the public

                     Final Index Value =   the closing value of the Nikkei 225
                                           on June 14, 2002

                                   However, if this amount is zero or less, we
                                   will not pay you a supplemental redemption
                                   amount. In other words, if the Nikkei 225
                                   does not go up over the life of the notes,
                                   you will not receive any supplemental
                                   redemption amount.

                                   should review the discussion in the
                                   accompanying prospectus supplement under

Nikkei 225 is currently            The last reported value of the Nikkei 225, as
at 16,338.70                       published by Nihon Keizai Shimbun, Inc. was
                                   16,338.70. You can review the publicly

                                   reflected in the level of the Nikkei 225
                                   and, therefore, has no effect on our
                                   calculation of the percentage increase in
                                   the Nikkei 225. The historical performance
                                   of the Nikkei 225 should not be taken as an
                                   indication of what its value will be at
                                   maturity.

The Calculation Agent              We have appointed Morgan Stanley & Co.
                                   International Limited, which we refer to as
                                   MSIL, to act as calculation agent for The

                                   agent, MSIL will determine the percentage
                                   change in the Nikkei 225, the final index
                                   value and the supplemental redemption
                                   amount.

                                  RISK FACTORS

     The notes are not secured debt and unlike ordinary debt securities do not
pay interest. This section describes the most significant risks relating to the
notes. You should carefully consider whether the notes are suited to your
particular circumstances before you decide to purchase them.


Notes are not ordinary             The terms of the notes differ from those of
senior notes                       ordinary debt securities in that we will not
                                   pay interest on the notes. Because the
                                   supplemental redemption amount due at
                                   maturity may be equal to zero, the return on
                                   your investment (the effective yield to
                                   maturity) in the notes may be less than the
                                   amount that would be paid on an ordinary
                                   debt security. The return of only the
                                   principal amount of each note at maturity
                                   will not compensate you for any loss in
                                   value due to inflation and other factors
                                   relating to the value of money over time.

Notes may not                      If the percentage change in the Nikkei 225 is
pay more than par at               equal to or less than zero, you will receive
maturity                           only the par amount of $10,000 for each note
                                   that you hold at maturity.

actively traded                    There can be no assurance as to whether
                                   there will be a secondary market in the
                                   notes. If there is a secondary market, it
                                   may not provide enough liquidity to allow
                                   you to trade or sell the notes easily. MSIL
                                   currently intends to act as a market-maker
                                   for the notes, but is not required to do so.
                                   If MSIL does make a market in the notes, it
                                   may stop doing so at any time without
                                   notice.

Market price of the notes          Several factors, many of which are beyond our
influenced by many                 control, will influence the value of the
unpredictable factors              notes, including:

                                   o the value of the Nikkei 225

                                   o interest and yield rates in the market

                                   o the volatility (frequency and magnitude of
                                     changes in price) of the Nikkei 225

                                   o economic, financial, political and
                                     regulatory or judicial events that
                                     affect the securities underlying the
                                     Nikkei 225 or stock markets generally
                                     and which may affect the final index
                                     value

                                   o the time remaining to the maturity of the
                                     notes

                                   o the dividend rate on the stocks underlying
                                     the Nikkei 225

                                   o our creditworthiness

                                   Some or all of these factors will influence
                                   the price that you will receive if you sell
                                   your notes prior to maturity. For example,
                                   you may have to sell your notes at a
                                   substantial discount from the principal
                                   amount if at the time of sale the Nikkei 225
                                   is at, below, or not sufficiently above the
                                   initial index value or if market interest
                                   rates rise.

                                   You cannot predict the future performance of
                                   the Nikkei 225 based on its historical
                                   performance. We cannot guarantee that the
                                   value of the Nikkei 225 will increase so
                                   that you will receive at maturity an amount
                                   in excess of the principal amount of the
                                   notes.

Adjustments to the Nikkei          Nihon Keizai Shimbun, Inc., which we refer to
225 could adversely affect         as NIKKEI, is responsible for calculating and
the notes                          maintaining the Nikkei 225.  NIKKEI can add,
                                   delete or substitute the stocks underlying
                                   the Nikkei 225 or make other methodological
                                   changes that could change the value of the
                                   Nikkei 225. NIKKEI may discontinue or
                                   suspend calculation or dissemination of the
                                   Nikkei 225. Any of these actions could
                                   adversely affect the value of the notes.

Potential conflicts of             As calculation agent, MSIL will calculate the
interest between you               amount paid to you at maturity of the notes.
and the Calculation                MSIL and other affiliates may carry out
Agent                              activities that minimize our risks related
                                   to notes, including trading in the
                                   individual stocks included in the Nikkei 225
                                   as well as in other instruments related to
                                   the Nikkei 225. MSIL and some of our other
                                   subsidiaries also trade the individual
                                   stocks included in the Nikkei 225 and other
                                   financial instruments related to the Nikkei
                                   225 on a regular basis as part of their
                                   general broker-dealer businesses. Any of
                                   these activities could influence MSIL's
                                   determination of calculations made with
                                   respect to the notes and, accordingly, could
                                   affect your payout on the notes.

                                   Because MSIL calculates the percentage
                                   change in the Nikkei 225, the final index
                                   value and the supplemental redemption
                                   amount, potential conflicts of interest may
                                   exist between MSIL as calculation agent and
                                   you as an owner of the notes.

Investment in the notes            The payment of dividends on the stocks which
not the same as an                 compose, or underlie, the Nikkei 225 has no
investment in the                  effect on the calculation of the percentage
the Nikkei 225 stocks              change in the Nikkei 225. For this reason,
                                   and because the supplemental redemption
                                   amount includes a participation factor, the
                                   return on your investment based on the
                                   percentage change in the Nikkei 225 is not
                                   the same as the total return based on the
                                   purchase of those underlying stocks held for
                                   a similar period.

Potential risks of investing       An investment in the notes involves
in a security linked to foreign    considerations that may not be associated
common stock                       with a security linked to an index of stocks
                                   issued by companies organized in your local
                                   jurisdiction. These considerations relate to
                                   foreign market factors generally and may
                                   include, for example, different accounting
                                   requirements and regulations, different
                                   securities trading rules and conventions,
                                   different and in some cases more adverse
                                   economic environments, like the recession
                                   experienced by the Japanese economy and
                                   other Asian economies, and greater
                                   governmental involvement in the economy and,
                                   in some cases, greater volatility and
                                   unpredictability.

Tax treatment                      You should also consider the tax
                                   consequences of investing in the notes.

                                   The Calculation Agent will round all
                                   percentages resulting from any calculation
                                   with respect to the notes to the nearest one
                                   hundred- thousandth of a percentage point,
                                   with five one-millionths of a percentage
                                   point rounded upwards (e.g., 9.876545% (or
                                   .09876545) would be rounded to 9.87655% (or
                                   .0987655)). All dollar amounts used in or
                                   resulting from such calculation will be
                                   rounded to the nearest tenth of a cent with
                                   five tenths of a cent being rounded upwards.

Nikkei 225 Percent Change......... The Nikkei 225 Percent Change is a fraction,
                                   the numerator of which will be the Final
                                   Index Value less the Initial Index Value and
                                   the denominator of which will be the Initial
                                   Index Value. The Nikkei 225 Percent Change
                                   is described by the following formula:

                                    (Final Index Value - Initial Index Value)
                                   --------------------------------------------
                                              Initial  Index Value

Initial Index Value............... 16,338.70

Final Index Value................. The Final Index Value will be the Index
                                   Closing Value on June 14, 2002.

                                   If a Market Disruption Event occurs on June
                                   14, 2002 or if that day is not a Trading
                                   Day, the Final Index Value will be
                                   determined on the immediately succeeding
                                   Trading Day during which no Market
                                   Disruption Event occurs; provided that the
                                   Final Index Value will not be determined on
                                   a date later than the second scheduled
                                   Trading Day preceding the Maturity Date, and
                                   if such date is not a Trading Day, or if
                                   there is a Market Disruption Event on such
                                   date, the Calculation Agent will determine
                                   the value of the Nikkei 225 on such date in
                                   accordance with the formula for and method
                                   of calculating the Nikkei 225 in effect on
                                   the last Trading Day on which no Market
                                   Disruption Event occurred, using the closing
                                   price (or, if trading in the relevant
                                   securities has been materially suspended or
                                   materially limited, its good faith estimate
                                   of the closing price that would have
                                   prevailed but for such suspension or
                                   limitation) on such date of each security
                                   most recently constituting the Nikkei 225.

Index Closing Value............... The Index Closing Value will equal the
                                   closing value (afternoon session) of the
                                   Nikkei 225, published by NIKKEI, on a
                                   specified date. See "--Discontinuance of the

                                   to the Nikkei 225 will include any Successor
                                   Index, unless the context requires
                                   otherwise.

                                        Successor Index) on the Relevant
                                        Exchanges for such securities for more
                                        than two hours of trading or during the
                                        one-half hour period preceding the
                                        close of trading (afternoon session) in
                                        such market or a breakdown or failure
                                        in the price and trading systems of any
                                        Relevant Exchange as a result of which

                                        last one-half hour preceding the
                                        closing of trading (afternoon session)
                                        on such Relevant Exchange are
                                        materially inaccurate; or the
                                        suspension, material limitation or
                                        absence of trading on any major
                                        securities exchange or market of
                                        trading in futures or options contracts
                                        related to the Nikkei 225 (or the
                                        relevant Successor Index) for more than
                                        two hours of trading or during the
                                        one-half hour period preceding the
                                        close of trading on such market; and

                                        (ii) a determination by the Calculation
                                        Agent in its sole discretion that any
                                        event described in clause (i) above
                                        materially interfered with the ability
                                        of MSDW or any of its affiliates to
                                        unwind all or a material portion of the
                                        hedge with respect to the notes.

                                   For the purpose of determining whether a
                                   Market Disruption Event exists at any time,
                                   if trading in a security included in the
                                   Nikkei 225 is materially suspended or
                                   materially limited at that time, then the
                                   relevant percentage contribution of that
                                   security to the level of the Nikkei 225
                                   shall be based on a comparison of (x) the
                                   portion of the level of the Nikkei 225
                                   attributable to that security relative to
                                   (y) the overall level of the Nikkei 225, in
                                   each case immediately before that suspension
                                   or limitation.

                                   For purposes of determining whether a Market
                                   Disruption Event has occurred: (1) a
                                   limitation on the hours or number of days of
                                   trading will not constitute a Market
                                   Disruption Event if it results from an
                                   announced change in the regular business
                                   hours of the relevant exchange or market,
                                   (2) a decision to permanently discontinue
                                   trading in the relevant futures or options
                                   contract will not constitute a Market
                                   Disruption Event, (3) limitations pursuant
                                   to the rules of any Relevant Exchange
                                   similar to NYSE Rule 80A (or any applicable
                                   rule or regulation enacted or promulgated by
                                   any other self-regulatory organization or
                                   any government agency of similar scope as
                                   determined by the Calculation Agent) on
                                   trading during significant market
                                   fluctuations will constitute a suspension,
                                   absence or material limitation of trading,
                                   (4) a suspension of trading in a futures or
                                   options contract on the Nikkei 225 by the
                                   primary securities market related to such
                                   contract by reason of (a) a price change
                                   exceeding limits set by such exchange or
                                   market, (b) an imbalance of orders relating
                                   to such contracts or (c) a disparity in bid
                                   and ask quotes relating to such contracts
                                   will constitute a suspension or material

                                   a suspension, absence or material limitation

                                   options contracts related to the Nikkei 225
                                   are traded will not include any time when
                                   such market is itself closed for trading
                                   under ordinary circumstances.

                                   the Calculation Agent will determine the
                                   amount declared due and payable upon any
                                   acceleration of the notes, which will be
                                   equal to $10,000 plus the Supplemental

                                   though the date on which the Final Index

                                   of manifest error, be conclusive for all
                                   purposes and binding on you and on us.

                                   Because the Calculation Agent is our

                                   make in determining the Nikkei 225 Percent
                                   Change, the Final Index Value, the
                                   Supplemental Redemption Amount or whether a

                                   The Nikkei 225 is a stock index calculated,
                                   published and disseminated by NIKKEI that
                                   measures the composite price performance of
                                   selected Japanese stocks. The Nikkei 225
                                   currently is based on 225 highly capitalized
                                   underlying stocks (the "Underlying Stocks")
                                   trading on the TSE representing a broad
                                   cross-section of Japanese industries. All
                                   225 Underlying Stocks are stocks listed in
                                   the First Section of the TSE. Domestic
                                   stocks admitted to the TSE are assigned to
                                   either the First Section or Second Section.
                                   Stocks listed in the First Section are among
                                   the most actively traded stocks on the TSE.
                                   At the end of each business year, the TSE
                                   examines each First Section stock to
                                   determine whether it continues to meet the
                                   criteria for inclusion in the First Section
                                   and each Second Section stock to determine
                                   whether it may qualify for inclusion in the
                                   First Section.

                                   The Nikkei 225 is a modified, price-weighted
                                   index (i.e., an Underlying Stock's weight in
                                   the index is based on its price per share
                                   rather than the total market capitalization
                                   of the issuer) which is calculated by (i)
                                   multiplying the per share price of each
                                   Underlying Stock by the corresponding
                                   weighting factor for such Underlying Stock
                                   (a "Weight Factor"), (ii) calculating the
                                   sum of all these products and (iii) dividing
                                   such sum by a divisor (the "Divisor"). The
                                   Divisor was initially set at 225 for the
                                   date of May 16, 1949 using historical
                                   numbers from May 16, 1949, the date on which
                                   the Tokyo Stock Exchange was reopened. The
                                   Divisor was 20.341 as of June 14, 2000 and
                                   is subject to periodic adjustments as set
                                   forth below. Each Weight Factor is computed
                                   by dividing (Y)50 by the par value of the
                                   relevant Underlying Stock, so that the share
                                   price of each Underlying Stock when
                                   multiplied by its Weight Factor corresponds
                                   to a share price based on a uniform par
                                   value of (Y)50. The stock prices used in the
                                   calculation of the Nikkei 225 are those
                                   reported by a primary market for the
                                   Underlying Stocks (currently the TSE). The
                                   level of the Nikkei 225 is calculated once
                                   per minute during TSE trading hours.

                                   In order to maintain continuity in the
                                   Nikkei 225 in the event of certain changes
                                   due to non-market factors affecting the
                                   Underlying Stocks, such as the addition or
                                   deletion of stocks, substitution of stocks,
                                   stock splits or distributions of assets to
                                   stockholders, the Divisor used in
                                   calculating the Nikkei 225 is adjusted in a
                                   manner designed to prevent any instantaneous
                                   change or discontinuity in the level of the
                                   Nikkei 225. Thereafter, the Divisor remains
                                   at the new value until a further adjustment
                                   is necessary as the result of another
                                   change. As a result of such change affecting
                                   any Underlying Stock, the Divisor is
                                   adjusted in such a way that the sum of all
                                   share prices immediately after such change
                                   multiplied by the applicable Weight Factor
                                   and divided by the new Divisor (i.e., the
                                   level of the Nikkei 225 immediately after
                                   such change) will equal the level of the
                                   Nikkei 225 immediately prior to the change.

                                   An Underlying Stock may be deleted or added
                                   by NIKKEI. Any stock becoming ineligible for
                                   listing in the First Section of the TSE due
                                   to any of the following reasons will be
                                   deleted from the Underlying Stocks: (i)
                                   bankruptcy of the issuer, (ii) merger of the
                                   issuer with, or acquisition of the issuer
                                   by, another company, (iii)

                                   delisting of such stock, (iv) transfer of
                                   such stock to the "Seiri-Post" because of
                                   excess debt of the issuer or because of any
                                   other reason (v) transfer of such stock to
                                   the "Kanri-Post" (Posts for stocks under
                                   supervision) or (vi) transfer of such stock
                                   to the Second Section. In addition,
                                   Underlying Stocks with relatively low
                                   liquidity, based on trading volume and price
                                   fluctuation over the past ten years, may be
                                   deleted by NIKKEI subject to a maximum of
                                   six such deletions by reason of low
                                   liquidity per year. Upon deletion of a stock
                                   from the Underlying Stocks, NIKKEI will
                                   select a replacement for such deleted
                                   Underlying Stock in accordance with certain
                                   criteria. In an exceptional case, a newly
                                   listed stock in the First Section of the TSE
                                   that is recognized by NIKKEI to be
                                   representative of a market may be added to
                                   the Underlying Stocks. In such a case, an
                                   existing Underlying Stock with low trading
                                   volume and deemed not to be representative
                                   of a market will be deleted by NIKKEI.

                                   A list of the issuers of the Underlying
                                   Stocks constituting Nikkei 225 is available
                                   from the Nikkei Economic Electronic Databank
                                   System and from the Stock Market Indices
                                   Data Book published by NIKKEI. NIKKEI may
                                   delete, add or substitute any stock
                                   underlying the Nikkei 225.

                                   NIKKEI first calculated and published the
                                   Nikkei 225 in 1970. The following table sets
                                   forth the high, the low and the closing
                                   values of the Nikkei 225 for each quarter in
                                   the period from January 1, 1995 through June
                                   14, 2000, as published by NIKKEI. The
                                   historical performance of the Nikkei 225
                                   should not be taken as an indication of
                                   future performance, and no assurance can be
                                   given that such performance, taken together
                                   with the performance of the stocks
                                   underlying the Nikkei 225, will cause the
                                   holders of the notes to receive any
                                   Supplemental Redemption Amount under the
                                   formula for determining the Supplemental

Discontinuance of the Nikkei 225;
Alteration of Method of
Calculation....................... If NIKKEI discontinues publication of the
                                   Nikkei 225 and NIKKEI or another entity
                                   publishes a successor or substitute index
                                   that the Calculation Agent determines, in
                                   its sole discretion, to be comparable to the
                                   discontinued the Nikkei 225 (such index
                                   being referred to herein as a "Successor
                                   Index"), then any subsequent Index Closing
                                   Value will be determined by reference to the
                                   value of such Successor Index at the close
                                   of trading on relevant exchange or market
                                   for the Successor Index on the date that the
                                   Final Index Value is to be determined.

                                   Upon any selection by the Calculation Agent
                                   of a Successor Index, the Calculation Agent
                                   will cause written notice thereof to be
                                   furnished to the Trustee, to MSDW and to the
                                   holders of the notes within three Trading
                                   Days of such selection.

                                   If NIKKEI discontinues publication of the
                                   Nikkei 225 prior to, and such discontinuance
                                   is continuing on, the date that the Final
                                   Index Value is to be determined and the
                                   Calculation Agent determines that no
                                   Successor Index is available at such time,
                                   then on such date, the Calculation Agent
                                   will determine the Index Closing Value that
                                   would be used in computing the Nikkei 225
                                   Percent Change on such date. The Index
                                   Closing Value will be computed by the
                                   Calculation Agent in accordance with the
                                   formula for and method of calculating the
                                   Nikkei 225 last in effect prior to such

                                   comprising the Nikkei 225. Notwithstanding
                                   these alternative arrangements,
                                   discontinuance of the publication of the
                                   Nikkei 225 may adversely affect the value of
                                   the notes.

                                   If at any time the method of calculating the
                                   Nikkei 225 or a Successor Index, or the
                                   value thereof, is changed in a material
                                   respect, or if the Nikkei 225 or a Successor
                                   Index is in any other way modified so that
                                   such index does not, in the opinion of the
                                   Calculation Agent, fairly represent the
                                   value of the Nikkei 225 or such Successor
                                   Index had such changes or modifications not
                                   been made, then, from and after such time,
                                   the Calculation Agent will, at the close of
                                   business in New York City on the date that
                                   the Final Index Value is to be determined
                                   make such calculations and adjustments as,
                                   in the good faith judgment of the
                                   Calculation Agent, may be necessary in order
                                   to arrive at a value of a stock index
                                   comparable to the Nikkei 225 or such
                                   Successor Index, as the case may be, as if
                                   such changes or modifications had not been
                                   made, and calculate the Supplemental
                                   Redemption Amount with reference to the
                                   Nikkei 225 or such Successor Index, as
                                   adjusted. Accordingly, if the method of
                                   calculating the Nikkei 225 or a Successor
                                   Index is modified so that the value of such
                                   index is a fraction of what it would have
                                   been if it had not been modified (e.g., due
                                   to a split in the index), then the
                                   Calculation Agent will adjust such index in
                                   order to arrive at a value of the Nikkei 225
                                   or such Successor Index as if it had not
                                   been modified (e.g., as if such split had
                                   not occurred).

Use of Proceeds and Hedging....... The net proceeds we receive from the sale of
                                   the notes will be used for general corporate
                                   purposes and, in part, by us or one or more
                                   of our affiliates in connection with hedging
                                   our obligations under the notes, including
                                   hedging market risks associated with the
                                   Supplemental Redemption Amount.

                                   On the date of this pricing supplement, we,
                                   through our subsidiaries or others, hedged
                                   our anticipated exposure in connection with
                                   the notes by the purchase and sale of
                                   exchange traded and over-the-counter options
                                   on the Nikkei 225, individual stocks
                                   included in the Nikkei 225, futures
                                   contracts on the Nikkei 225 and options on
                                   such futures contracts or by taking
                                   positions in any other instruments that we
                                   wished to use in connection with such
                                   hedging. Through our subsidiaries, we are
                                   likely to modify our hedge position
                                   throughout the life of the notes, including
                                   on the date that the Final Index Value is to
                                   be determined, by purchasing and selling the
                                   securities and instruments listed above and
                                   any other available securities and
                                   instruments that we may wish to use in
                                   connection with our hedging activity.
                                   Although we have no reason to believe that
                                   our hedging activity had or will have a
                                   material impact on the price of such
                                   options, stocks, futures contracts, and
                                   options on futures contracts or on the value
                                   of the Nikkei 225, we cannot give any
                                   assurance that we did not, or in the future
                                   will not, affect such prices as a result of
                                   our hedging activities.
